| Abstract: | A simple and rapid detection method of carnauba wax in granular gums and chocolate beans has been developed by high-temperature gas chromatography (HT-GC).Standard solution is directly derived by trimethylchlorosilane (BSTFA),and samples,respectively,are extracted by ultrasonic heating,derived with BSTFA and then detected with hydrogen flame ionization detector (FID).Carnauba wax-related components are positively detected in five samples.Finally,the content of carnauba wax in samples is rough estimated. |
